Before starting treatment, what must the hygienist obtain from the patient?

• A. The patient's permission to perform the described procedures before starting.
• B. Consent is optional if the patient is in pain.
• C. The patient must sign a health history form only.
• D. Pre-treatment consent is not required in dental hygiene.

Answer: (A)

Informed consent is the concept being tested. Before starting any treatment, the hygienist must obtain the patient’s permission to perform the planned procedures after explaining what will be done, why it’s recommended, the possible risks and benefits, and any alternatives. This respects patient autonomy and provides legal protection for both patient and clinician. It isn’t enough to rely on a health history form or to assume consent just because the patient is in pain. Consent must be obtained prior to treatment, and if the patient cannot consent themselves (such as a minor or someone unable to decide), a parent, guardian, or legally authorized representative must provide it. Documentation of the consent is also important.
